Standing on the corner of Melbourne Avenue and North Powers Drive, he sobbed over the death of his son while others tried to console him.

"Oh 'Twon," the father whispered, repeatedly, in between tears. "Oh 'Twon."

Dozens of onlookers gathered as deputies investigated the scene.

Traffic moved slowly up and down Powers Drive as curious motorists lowered their windows to see what was going on the street lined with bungalow-style homes.

Jeanette Wimberly-Walker, the victim's stepmother, said they were in Sanford when they learned about the fatal shooting.

"We were out shopping and we just got the call that he was shot, and that he didn't make it," Wimberly-Walker said.

She said her stepson was a loving and caring person. He grew up on the block, and still had friends there, family said.

"I only knew good things about him," Wimberly-Walker said. "He was very respectful toward me."

Court records show Walker Jr. was convicted of four offenses: aggravated assault in 1999, possession of a controlled substance in 2006 and misdemeanor possession of marijuana in 2008 and 2009. He spent less than one year in jail combined for each conviction.
